At the end of the car. the end mor sheet l is 7 supported on and riveted or otherwise rigidly' secured to the outstanding top flange of, an end angle 1, whosedepending inner s idejange is riveted or otherwise rigidly secured. to the up- 5 standing inner side flange of an end plate 8'.

'Ihe roof is provided with one or morevv hatchways that lead downwardly into the interior of the car through the end-sheet and a framework Y located therebelow. .Saidframework 'comprises l0 spaced parallel frame or carline members l that extend from side plate to side plate with their ends rigidly secured thereto and themselves supporting. spaced cross frame members lli. The carline members and cross members preferably 15. comprise oblique metal anlesfarranged with. their tops flush and with th il' sides converging downwardly. Each hatchway is provided with a metalframe comprising a hopper portion l2 that yextends 20 downwardly through the opening defined by the I frame members 9` and I0 with its downwar converging sides restingmatwise against the in- Said hopper portion'alsoroof sheets where it is provided with an exterior. nllow rim portion Il formed by a flange that extends outwardly from the upper end thereof and thence downwardlyaround sides thereof with its lower end, spaced so above the general level of the end roof or hatch sheet I. The hollow rim portion Il of the metal hatch frame is reinforced and stiiened along its four sides by `means of upright plates Il that rest upon the tops of the angle iron frame members 9 and I0 and extend upwardly into said rim and have a snug fit therein. The plates Il are welded, as at I5, along their edges to the' portions of the hatch frame in contact therewith and are 'also tack-welded, as at IB, at their lower edges 40 to the tops of the frame members 9 and III. '111e lower portions of the plates Il 'are widened to bring the outer edges I1 thereof infiush alineposea substanueny in the plane of the lower edge of said rim portion and with its inner facehdisposed substantially in flush alinement with the outer face of the depending outer wall thereof.

The upstandinghatch sheetange It is rigidly secured to the depe dingouter wall of the v In the 'modified construction shown in Fig. 7, the upper end of the hopper portion of the metal hatch frame isprovided with a mere outstanding iiange and the upstanding iange |8a alongV the margin of the opening in the hatch sheet has v its upper edge disposed substantially iush withl the underside of said outstanding flange. The

roof vsheet flange and hatch sheet ange are secured together by a weld 19a of added metal that extends, along the adjacent edges of said flanges.

In Vthe modified construction shown in Fig. 8, the top flange 2| of the metal hatch frame is made narrower than the top flange 20 of the hatch frame shown in Fig. 7; and the upstanding hatch sheet flange is provided at its top with an inwardly extending portion I8b that abuts edgewise against the outer edge of the hatch frame an'ge. The hatch frame flange and roof sheet ange are rigidly secured together by a weld |9b of added metalthat extends along the tops of said flanges above the joint therebetween.

In the modified construction shown in Fig. 9,

vthe metal hatch frame is made without a topv flange and the hatch sheet ange has an inwardly extending portion |80 at its upper end that is disposed flush with the upperof said hatch frame and abuts edgewise against the side thereof. The metal hatch frame and roof sheet flange are secured together by a weld lilov of. added metal that covers thejoint therebetween. The modified form of hatch construction shown in Figs. 10 to l5, inclusive, is'simila'r to that shown in Figs. 1 to 6, inclusive, except that the carline members and the crdss members of the' hatch supporting framework or carline assembly have their outer marginal portions of their top flanges ybent Vup opposite the hatch opening in said of said wall.

framework to form upstanding flanges 22 that are disposed in line with the depending outer wall of the hollow hatch frame rim, with their upper edges spaced slightly below the. lower edge A weld 23 lls the spaces between the opposing edges of the upstanding frame member flanges 22 and the edge of the depending outer wall of the hollow hatch frame rim and thus serves to rigidly secure said metal hatch frame to the supporting framework therefor.

. The upstanding flange I 8d along the margin of the vopening in the hatch sheet is secured along its upper edgelto the lower end of the outer wall` of the hatch frame rim by means of a weld ISd that forms a rigid weatherproof connection be-` tween the hatch frame and hatch sheet.

The hatch construction hereinbefore described has numerous advantages. The cross plates in the hollow rim portion of the metal hatch frame serve as-ties and struts for preventing distortion thereof; they also serve to locate the lower edge of the outer wall of the hollow hatch frame rim level with the upper edge of the hatch sheet flange and to bring the outer surface of said wall and the inner surface `of saidY iiange'in flush alinement' so that said wall and said ange may be welded together in proper relation; and they also afford means for welding the hatch vframe tothe supporting framework therefor. The metal f hatch frame can be applied to the car with the framework as Aa. separate unit, .or it may be welded to the framework after the latter is applied to the car.

The hatch sheet can be removed without removing the hatch frame; and,

likewise. the hatch (fr-ame can be removed without removing the hatch sheet. In the hatch construction shown in Figs. 10 to 15, inclusive, the upwardly flanged margins of the top anges of the frame members of the framework provide means for welding thehatch frame thereto and they also serve to properlyposition the Vhatch sheet ange: relative to the depending outer' wall of the hatch frame rim. -What I claim is: y
